Is it possible to pass --build-arg LEnv=dev UEnv=Dev while building and running docker together using Docker-compose

Question

I am using this below command to run my docker containers and want to pass --build-arg LEnv=dev UEnv=Dev in this same command.

docker-compose -f docker-compose.yml up --build --force-recreate

Want to read this arg in docker-Compose file:

Does this answer your question? [How to define build-args in docker-compose?](https://stackoverflow.com/questions/50734271/how-to-define-build-args-in-docker-compose) — jonrsharpe, Jun 11 '20 at 07:54
Or maybe [this one](https://stackoverflow.com/questions/49293967/how-to-pass-environment-variable-to-docker-compose-up/50991623#50991623). — Lucas Campos, Jun 11 '20 at 07:55
@jonrsharpe Trying to use --build-arg as below : docker-compose -f docker-compose.yml up --build --force-recreate --build-arg LEnv=dev --build-arg UEnv=Dev — amit singh, Jun 11 '20 at 08:05
Well you can see the `docker-compose up` CLI reference [here](https://docs.docker.com/compose/reference/up/), it doesn't take `--build-arg`. But you can pass build args to the containers as shown in the dupe I proposed, and use variable substitution to pass values into the compose file as shown in the file reference [here](https://docs.docker.com/compose/compose-file/#variable-substitution). — jonrsharpe, Jun 11 '20 at 08:15
You seem to have attached an image to your question instead of the text of your `docker-compose.yml` file; can you replace the image with the actual YAML? Can you clarify what specific problem you're running into (is it just that you can't pass `docker-compose up --build-arg`, or are you having a different problem)? — David Maze, Jun 11 '20 at 09:52

You can not pass --build-arg to docker-compose up command. as these are the flag/options of docker-compose build.

but you utilize environment variable

version: "3.8"
services:
  webapp:
    build:
      context: ./
      dockerfile: Dockerfile
      args:
        buildno: ${buildno}

and then run

buildno=2 docker-compose up --build

you can check possible flag/option using below command.

docker-compose build --help
Build or rebuild services.

    --build-arg key=val     Set build-time variables for services.
    --compress              Compress the build context using gzip.
    --force-rm              Always remove intermediate containers.

                            EXPERIMENTAL flag for native builder.
                            To enable, run with COMPOSE_DOCKER_CLI_BUILD=1)
    --pull                  Always attempt to pull a newer version of the image.
    -q, --quiet             Don't print anything to STDOUT
